The Influence Of High-Intensity Interval Exercise On Vitamin-D Concentrations In Healthy Individuals, Leroy K. Bolden, Tomas Chapman-Lopez, Ricardo Torres, Jeffery Heileson, Meena Meiyyappan, Jeff S. Forsse
International Journal of Exercise Science: Conference Proceedings
Vitamin D (VD) deficiency is one of the most common deficiencies in the world due to various factors (e.g., lack of sun exposure, dietary considerations). Currently the utilization of exercise may act as an intervention for VD deficiencies to promote increases in VD concentrations in healthy populations. This could largely be due to the loss of calcium from aerobic exercise (AE), leading to a hormonal response [(e.g., parathyroid hormone (PTH)] and the activation of cytochrome’s (e.g., CYP2R1, CYP27B1) responsible for the regulation of VD. Thus, AE may serve as an intervention to promote VD synthesis due to the impacted biological …

Validation Of A Non-Invasive Physiological Stress Assessment: Agreement Of Salivary And Blood Cortisol Among Firefighters, Caiti Dodge, Hunter Martaindale, Steven E. Martin, Lisa C. Colvin, Drew E. Gonzalez, Matthew J. Mcallister
International Journal of Exercise Science: Conference Proceedings
Salivary cortisol has been used as an indicator of stress exposure among tactical personnel (i.e., firefighters). Assessing cortisol concentrations, whether via blood or saliva samples, can provide valuable insight into the physiological stress load placed upon the firefighter. Cortisol levels provide a reflection of the hypothalamic-pituitary-adrenal (HPA) axis activity. Salivary cortisol is unbound and has been suggested to provide a better reflection of HPA axis activity compared to blood cortisol, which is bound to soluble corticosteroid-binding globulin. Importantly, the use of salivary biosample collection also offers a more practical and non-invasive method to assess physiological stress biomarkers when blood sample …
